The block storing method (BSM) based on Morton Key ordering for the efficient storage of the near group interaction matrix in the multilevel fast multipole algorithm (MLFMA) is presented. The proposed method is applied in a parallel MLFMA and a scattering problem with nearly 5 300 000 unknowns is solved, for which the BSM saves 6.84 GB without any extra cost.
